I had to take my PCM to their shop in Sanford Fl, and they fixed the PCM so the truck would run. The Tuner wouldn't work on my truck after that but it will work on other trucks just fine. So I made a bench harness and tried it and still nothing. I have had trouble communicating with the PCM ever since the failed tune.

I haven't licensed my PCM with my HP tuners yet because I dont want to waste any credits. I have read the PCM with VCM editor no problem and I'm thinking about changing out my PCM with another one. I have a few PCMs with the same hardware number.

How exact of a match does the "new" PCM need to be?

Can I just license the "new" PCM and write my stock file to it for 2 credits?

Does the VIN need to be correct for the BCM or anything like that?

Can I change the VIN to match the truck? Does that take 2 more credits?

Would like someone to go over my current base tune to make sure I didn't miss anything. I've attached the base tune, scan log, and channel config.

My project and problem is I did a 24X LS2 swap into my Porsche 997 (see link below). The issue and question I have is what do I need to set the high and low resolutions to in VCM editor to get my tach to work correctly? Currently set at 6 and 6 which obviously does not work. I was reading some other post for 6 cylinder swaps that people were using 3 and 3 on the high and low but thinking the Porsche might be needing to see different settings. Porsche from what I understand is 58X so need to know how to make my 24x look like a 58x for a 6 cylinder tach if that makes any sense.

Anyone with expeience or advise I am ready to give it a try. Thanks

(383, AA kit, big cam, etc) There are a fewreasons I want to go this route. The first being I already have hpt and enjoy feeling like a part of the process. Second is I need to break in both the brand new engine and clutch and the tuners around me disagree and want to throw it on a dyno right away. I also do not want to feel like I am married to a particular tune and spend hundreds of dollars if I want to tweak something.

My question is for knowledge as I do not have a problem with the car...

In my stoich AFR table I have odd values compared to what I see for others who just have the basic stoich values in this table.

Can anyone help me understand why my tuners values are what they are and why?
Im trying to teach myself Lamda based tuning but not sure whats happening with this table

Thought it was my wideband sensor going out but after actually feeling/smelling the issue happening i ran some logs on it.

Vehicle is an 06 silverado with the 4.8, has a spectre intake and speed engineering long tubes.

When driving it my wideband will suddenly go to a 16.0 reading and hold there, then it will swing to a 13.0 reading and stay. After a few minutes of this it will go back to acting normally. A few more miles and the process repeats. Giving more throttle when its lean or rich to get into what should be the PE area it will finally command for 12.5 af and WB shows it is getting there. Once throttle is reduced to normal cruise it will go back into being either super lean or rich. Truck has been driving fine without issue on this tune for months. Logs show that the 16.0 and 13.0 AFR is actually being commanded for some reason. This all came out of nowhere one morning when driving to work and as long as the AFR is right truck still runs perfect. Checked for basic mechanical issues and looked over all the plugs/wires for the O2 sensors and cant find anything obviously wrong.

My brother wants to power brake his truck and burn rubber. When we try his RPM's rise to about 1800 and that's it. Almost like it's hitting a limiter. I've tried multiple settings with transmission abuse and it appears to me that all torque management is removed. Would someone be willing to take a look at this tune file and see what I'm missing?

Misc info - truck does not have a traction control button, tire size/rim size is stock (17), tread is highway, torque converter is stock, and no engine lights or mechanical problems.

I've tried every thing i can think of, idle spark, main spark, ve adjustments, idle air adjustments, over/ under spark.and nothing seems to work. if i put it in gear and let off the brake it will slowly pick up speed and clear up on ts own with no throttle.
this isnt my first time tuning a cammed vehicle, but it has me confused. any suggestions?redrocket rtt.hpt

I have a 2000 Corvette with 228/230 .585/.585 112 lsa Trickflow cam, stock intake with Haltech air bridge, stock z06 exhaust system, long tube headers, ls6 intake manifold. I made 363whp/365wtq on a Dynapack. My tuner did say his dyno reads low, but many people are saying I made low numbers even on a dynapack. My tuner does do good work and is very reputable. I was starting to think my cam might be off a tooth, but I kind of doubt it. Here's my dyno sheet, sorry it does not show the afr, but I will get the tune and log soon.20181113_213520 (1).jpg
